TUBULAR SKATE.

SPECIFICATION formingpart of Letters Patent No. 785,325, dated March 21, 1905. Application filed November 10 1903. Serial No. 180,542.

To all whom, it may concern:

Be it known that I, WILLIAM G. Now, of the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Tubular Skates, of which the following is a speci fication.

The object of my invention is to devise a simple, strong, and easily-manufactured tuthrough a hole in the main tube and brazedto the sides of the cone or strut above, substantially as hereinafter more specifically described and then definitely claimed.

Figure 1 is a side elevation of my improved skate. Fig. 2 is a plan view of the same. Fig. 8 is a cross-section on the line as y of Fig. 1.. Fig. 4 is a cross-section along the line a b in Fig. 1. Fig. 5 is a perspective view of the main tube and the connections.

In the drawings like letters of reference indicate corresponding parts in the different figures.

On referring particularly to Fig. 1 it will be noticed that my skate comprises as its main features a blade A, a main tube B, a heel-cone O, a sole-cone D, a toe-strut E, and a toe-plate F. The blade-is of the narrow form ordinarily employed for hockey and racing skates. The main tube B is split longitudinally along its lower edge, and flanges G are formed along the edges of the divisions. These flanges are preferably brazed or otherwise secured to-the upper portion of the blade.'

Through the upper surface of the tube are formed apertures, and about these apertures are brazed the lower ends of the cones O and D and the toe-strut E. These cones, it will be noticed, are spun with flanges H at their upper ends, through which are formed screwholes whereby the skate may be attached to a boot. It thus becomes unnecessary to peen or otherwise connect special plates to the cones through which to form the holes, as is now generally the case. If the two cones and toe-strut were simply brazed to the tube, the oints would not possess sufficient strength and, furthermore, the Weight of the skater would collapse the tube at these points. I therefore employ special connections at each of these points, as particularly shown in Fig. 5, each of which connections comprises a short tube I, longitudinally split along its upper edge, though the tubes might in some cases be completely divided. Integral with the tube at the edges I form lugs J These lugs extend up within the cones and are brazed or otherwise secured to their inner surfaces. (See Figs. 2 and 3.) The connection for the toe-strut is substantially similar, with the exception that as the toe-strut is tubular rather than conical the lugs are not spread, as is the case with the lugs for the cones.

that on reference to Figs. 2 and 4 the upper ends of the lugs J of the toe-strut connection pass through the toe-plate F and are peened outwardly to securely hold the toe plate against the upper end of the toe-strut. The toe-plate is also riveted or otherwise secured to the sole -cone D. The lugs J, it will be noticed, are suitably curved in cross-section so that they conform accurately to the configuration of the inner surfaces of the cones, so that when brazed thereto they form practically a portion of the said cones. These connections thus not only securely tie the cones and toe-strut to the tube of the skate, but as the tubes I substantially fill the main tube and contact with the top of the blade they effectually resist the crushing strain applied to the tube through the medium of the cones and toe-strut. Of course the construction described is most material with the heel and sole cones, as thegreatest strain comes upon them. The ends of the tube may be finished off as shown in Figspl and 2 or in any other desired manner.

The tubes I are shown as disconnected. I might, if it were so desired, form them all It will be noticed also from one piece, so that they would be all integrally connected, or the connections for the heel and sole cones alone might be so treated.

A skate constructed in accordance with my invention is not only very strong, but

is easily constructed, and different sizes of skates may be formed with the one set of dies, the blade and main tube being cut of any desired length and the holes for the connections of the toe and heel cones punched through at any desired positions for the size of skate to be made.

What I claim as my invention is 1. In a tubular skate the combination of a blade; a main tube divided longitudinally to embrace the blade and connected to the upper part of the same, an aperture being formed in its upper surface; a cone brazed to the tube about the aperture; and a connection comprising a split tubular portion brazed Within the main tube and lugs formed integral with the tubular portion extending up through the aperture and secured to the sides of the cone, substantially as described.

2. In a tubular skate the combination of a blade; a main tube dividedlongitudinally to embrace the blade and connected to the upper part of the. same, an aperture bein formed in its upper surface; a cone braze to the tube about the aperture; and a connection comprising a tubular portion split longitudinally along its upper side and brazed within the main tube in contact with the upper edge of the blade, and lugs formed integral with the tubular portion extending up through the aperture and secured to the sides of the cone, substantially as described.

3. In a tubular skate the combination of a blade; -a main tube divided longitudinally and having an aperture formed in its upper surface; flanges formed at the divided edges of the tube and secured to the upper part of the blade; a cone brazed to the tube about the aperture; and a connection comprising a tubular portion split longitudinally along its upper side and brazed within the main tube in contact with the upper edge of the blade, andlugs formed integral with the tubular portion extending up through the aperture and secured to the sides of the cone, substantially as described.

4. In a tubular skate the combination of a blade; a main tube divided longitudinally to embrace the blade and connected to the upper part of the same, an aperture being formed in its upper surface; a tubular toestrut brazed to the tube about the a erture; a connection comprising a split tubu ar portion brazed within the main tube, and lugs formed integral with the tubular portion and extending up through the tubular strut and peened over at the ends; and a toe-plate held between the end of the strut and the peenedover ends of the said lugs, substantially as described.

5. In a tubular skate the combination of a blade; a main tube divided longitudinally at its under side only to embrace the blade and connected to the upper part of the same; and one or more tubes brazed within the main tube above and in contact with the upper edge of the blade, substantially as described.

6. In a tubular skate the combination of a blade; a main tube divided longitudinally WILLIAM G. NOTT.
